I just got a new Acer Aspire 5740 2 days back. I installed Win7 Ultimate on it. I went to acer support site to find out any updated software on its site. There I found 2 updates for my bios. ver 1.10 http://global-download.acer.com/GDF...ep3=Aspire 5740&OS=722&LC=en&BC=Acer&SC=AAP_2 & ver 1.16 http://global-download.acer.com/GDF...ep3=Aspire 5740&OS=722&LC=en&BC=Acer&SC=AAP_2 My system has ver 1.09 Now I want to know what is the best way to update the bios. I came across some posts telling to do it in pure Dos rather than in windows. So how can one go to pure Dos. I believe the above Bios files already contains SLIC 2.1 can anybody confirm this. I also wanted to know one more thing. In the above bios files I am directed to start Flash.bat file which in turns calls KBC.bat which flashes/programs something then it calls Bios.bat which uses phlash16.exe to flash/program something. While searching on the forum for Bios modding people only refer to a single bios flashing application like phlash16.exe. Then why this update calling 2 apps to do the update. I am very much confused and would really appreciate if someone can enlighten me. Regards.
